Video Shader
Encyclopedia
Video Shader is a graphics card feature that ATI
advertises on their R300
and R400 cards. The R500 card is advertised as having Video Shader HD. Video shader is a feature that describes ATI's process of using Pixel Shaders to improve quality of video playback. It can also be used to perform post-processing
, like adding a film grain
, or adding other special effects.
One feature of Video Shader is ATI Full Stream. Full Stream detects the edges of video compression blocks and uses a pixel shader based filter to smooth the picture hiding the blocks. Another is Video Soap, which reduces video noise.
Other features are DXVA
support for Hardware Motion Compensation, iDCT, DCT and color space conversion. Support for Hardware Motion Compensation, iDCT, DCT and color space conversion is also listed.

Film grain
Film grain or granularity is the random optical texture of processed photographic film due to the presence of small particles of a metallic silver, or dye clouds, developed from silver halide that have received enough photons. While film grain is a function of such particles it is not the same...
